Abstract

PURPOSE:To improve reliability of wiring work, in earthquake-proof floor structure, where a beam is arranged on earthquake-proof supporting means arranged on a floor bed, and a floor member is laid on the beam, by arranging a wiring supporting member in such a manner that it crosses over a space between the beams. CONSTITUTION:Beams 35 are mounted on earthquake-proof supporting means arranged on a floor bed in a fixed arrangement, and a floor member is laid on the beams 35 to form earthquake-proof floor structure in which the floor member can move relatively to the floor bed. In the earthquake-proof floor structure, a wiring supporting member 41A is provided in such a manner that it crosses over a space between the beams 35 for attaching wires 42, 43 onto it. The wires 42, 43 laid in a underfloor space can therefore be prevented from rubbing on the floor bed or the like during the earthquake to secure reliability in a case of computer data transmission and the like.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a base isolation support device installed on the subfloor of a building, and a flooring material laid movably relative to the base floor using the base isolation support device. Regarding the type of seismic isolation floor structure.

[Conventional technology]

In order to maintain the reliability and durability of precision equipment such as computers and precision processing machines, even if seismic force (ground vibration) from an earthquake or passing vehicles acts on the building, the excitation force is not directly applied to the equipment. There is a demand for support through seismic isolation devices to prevent vibrations from being transmitted, and various seismic isolation floor structures for this purpose are being studied.

As this type of seismic isolation floor structure, for example, seismic isolation support means consisting of a large number of multi-layered laminated rubber assemblies arranged at predetermined intervals on the subfloor are installed, and beams are fixed thereon in a predetermined arrangement.
A structure in which flooring is laid on the beams has been proposed.

Such a seismic isolation floor structure is described, for example, in Japanese Patent Application Laid-Open No. 63-300
No. 160.

The seismic isolation support means exhibits a high spring constant in the longitudinal direction (vertical direction) but a soft spring constant in the lateral direction (horizontal direction), and has a low spring constant in the vertical direction with respect to earthquake force. There is almost no displacement in
00■) It has the characteristic of displacement.

On the other hand, the space between the flooring material and the subfloor (underfloor space)
In general, lighting equipment, air conditioners, computers, OA
Wiring for transmitting power and information for equipment, telephones, etc. is installed.

[Technical problem to be solved by the invention] However, in the conventional seismic isolation floor structure, these wirings extend between each of the beams (for example, from about 500 meters to about 3000 square meters if wide). Because it was directly supported on the beam, there was a possibility that it would sag between the beams, and if it were to sag and come into contact with the flooring, an earthquake could occur. When relative movement occurs between the flooring substrate and the flooring material, the wiring may rub against the flooring substrate, etc., and there is a risk that the wiring may be damaged or cut over time.

If the wiring is damaged, there is a possibility that computers, OA equipment, etc. will be seriously damaged.

The present invention has been made in view of such conventional technical problems, and can prevent chafing of wiring installed in the underfloor space, improve reliability in computer data transfer, etc. The purpose is to provide a seismic isolation floor structure that can be obtained.

[Means for solving problems]

In the present invention, beams are installed in a predetermined arrangement on seismic isolation support means arranged on a floor substructure, and flooring materials are laid on the beams, so that the flooring material can be moved relative to the floor substructure. In a seismically isolated floor structure that can be installed, the wiring support member for guiding or supporting the wiring is installed so as to straddle between the beams, so that it can be installed in the underfloor space even during an earthquake. The present invention provides a seismic isolation floor structure that can prevent wiring from rubbing against the flooring, etc., and can improve reliability in computer data transfer, etc.

〔Example] Hereinafter, the present invention will be specifically explained with reference to the drawings.

In Figures 3 and 4, the flooring (floor slab, etc.) 2
A seismic isolation floor structure 20 is constructed in a building consisting of a base 1 and a surrounding wall base (wall slough, etc.) 22.

The seismic isolation floor structure 20 has a floor surface consisting of a seismic isolation floor material (movable floor) 23 that can be displaced in the horizontal direction and a fixed floor material (fixed floor) 24 around the outside thereof, and the seismic isolation floor material 23 A buffer means 2 that provides a predetermined width interval between the periphery of the fixed floor material 24 and the inner surface of the fixed floor material 24, and absorbs horizontal relative displacement therebetween.
It is constructed by arranging 5.

On the inner peripheral part of the wall base 22 on the floor base 21, there is a fixed base 2 with a width that supports the buffer means 25, the outer periphery of the seismic isolation flooring 23, and the inner periphery of the fixed flooring 24.
6 is installed.

At least the seismic isolation floor material 23 and the buffer means 25 are supported horizontally movably on the upper surface of the fixed base 26.

The seismic isolation floor material 23 occupies most of the floor area, and is placed on the subfloor 21 by means of a seismic isolation support device consisting of a seismic isolation support means 27 and beams 35, 36, etc., which will be described below. Possibly supported.

The seismic isolation support device has a predetermined pitch (for example, 3 vertically and 3 horizontally).
Vertical and horizontal beams (frames) 35 are arranged at predetermined intervals on a plurality of multi-stage laminated rubber assemblies (seismic isolation support means) 27 arranged and fixed on the subfloor 21 with 000 pitches).
36 are connected, and seats (pedestals, etc.) 29 for supporting the flooring 23 are arranged on these beams 35 and 36 at a predetermined pitch.

The vertical and horizontal beams 35 and 36 are, for example, 500 to 1
They are arranged at intervals of 000 kaku.

A finishing material 30 is laid on the floor surface made up of the seismic isolation floor material 23, fixed floor material 24, and buffer means 25.

FIG. 5 is a side view showing details of the multi-stage laminated rubber assembly constituting the seismic isolation support means 27, and FIG. 6 is a sectional view taken along the line Vl--Vl in FIG. 5.

Each laminated rubber 31 has a structure in which a rubber-like elastic material and reinforcing plates such as steel plates or hard plastic plates are laminated and integrated in an alternating manner. Fastened and fixed.

The thus configured multi-stage laminated rubber assembly 27 is fixed to the floor subfloor 21 at its lower end, and the beam (frame) 35 (or 36) is fastened to its upper end.

FIG. 7 shows a state in which the multi-stage laminated rubber assembly 27 of FIG. 5 has been displaced in the horizontal direction due to an earthquake force or the like.

According to the multi-stage laminated rubber assembly 27 constructed by connecting the laminated rubber 31 as an element elastic body with the stabilizing plate 32 as shown in FIGS. Since it is restrained by , the structure as a whole becomes stable.

Therefore, even when seismic force acts, large horizontal displacements can be obtained without buckling as shown in Figure 7, and the support per unit is greater than when supporting with a single laminated rubber. The load can be greatly increased.

By using the multi-stage laminated rubber assembly 27 described above with reference to FIGS. 5 to 7, a large displacement (
For example, a maximum of 200 cm) can be obtained, but it shows a high deflection constant in the vertical direction and a small displacement (for example, 10 cm in the horizontal direction).
